You'r welcome. To be honest the Aluminum Lacquer seems to be of a grey tonality when looking at it. The glare effect would be a problem if the varnish was gloss... But judging by these shots above it was semi-matt or just matt coat rather.
No,no.. Bill. The cap above the indicator panel was black painted. The dark gray colour is a result of making these shots brighter in order to make these cockpit details more visible. Just the paint seems to be a matt one comparing to the one used on the cockpit sides.
And the next shot of the cockpit I found via the net...
